 /**
  * Simple implementation if the registry support functionality.
  * The logging output is done onto System.out (for both specific and generic logs)
  * in the following format:
  *
  * [Error|Warning|Log]: Main error message
  * [Error|Warning|Log]: Child error message 1
  * ...
  * [Error|Warning|Log]: Child error message N
  *
  * The translation routine assumes that keys are prefixed with '%'. If no resource
  * bundle is present, the key itself (without leading '%') is returned. There is
  * no decoding for the leading '%%'.
